1. IntroductionA hyperspectral image (HSI) is a special type of remote sensing image that can capture a very wide range of spectral bands [1,2,3], typically from the near-ultraviolet to the near-infrared wavelengths [1,3]. The resulting three-dimensional (3D) HSI data cube contains nearly continuous spectral profiles for each spatial resolution element [4], thereby allowing for more accurate quantification, identification, and discrimination of the imaged content [5].

AbstractMapping information from photographic images to volumetric medical imaging scans is essential for linking spaces with physical environments, such as in image-guided surgery. Current methods of accurate photographic image to computed tomography (CT) image mapping can be computationally intensive and/or require specialized hardware. For general purpose 3-D mapping of bulk specimens in histological processing, a cost-effective solution is necessary.
